The California Attorney General's office said in a letter Thursday that there was "insufficient evidence" to investigate Schumer. A Schumer spokesman declined to comment Saturday.

Some former IndyMac employees say Schumer's remarks in June 26 letters to regulators spurred a run on the bank that led to a government takeover. They want the senator to be prosecuted under a California law against making false statements about a bank's solvency.

Assistant Attorney General Thomas Greene said Schumer's statements were true and drawn from public information.
